Hedge-Fund Star Gets a Hip Check

Jeffrey Vinik's Tampa Bay Lightning are struggling, but the performance of his National Hockey League team isn't the only worry for the veteran stock-picker. Investors have asked to pull around $1.5 billion from his hedge-fund firm after a period of poor performance, according to people briefed on the matter.

The withdrawal requests amount to around 18% of the roughly $8 billion that was run by Vinik Asset Management.
